This is for a school project. Press the arrow keys to move around. When next to a wall, you can press the up arrow key and either the right or left arrow key to climb the wall. Press down to interact with objects if the down arrow key appears. Collect nine keys to unlock the nine questions to deposit into the brown box. Press space to switch between questions and to exit the notification that you received a key. I'm sorry if I sound choppy. I was in a hurry.
The string instrument art is credited to @EmberTail (yeah, I'm that bad at digital drawing). Song is "Bach Concerto in D Major" by J. S. Bach. Everything else is by me.
